Elena Morales was a citizen of Costa Rica. She worked as a nurse at the local hospital of Bahía Anasco. Early in the novel, Elena had a rushed conversation with Bobby Carter about the meaning of the word "hupia." Shortly after this, when a baby was killed by Procompsognathus during the night, she reported it as a case of Sudden Infant Death Syndrome. She did this to avoid being blamed for leaving the baby unattended.
